FUMIGATOR.

Application filed June 24,

'tilizedunder the application of heat.

The improved structure comprises a substantially self contained unitwhich embodies a stand or support, a heater, and a container fordisinfecting material. The stand has openings to maintain combustion andto properly direct the flame or heat about the container. The latter isequipped with *a flange whereby it is supported uponthe upper end of thestand, the flange, serving as a shield or deflector, to prevent theflameoi the heater from igniting the vapor issue ing from the containeroutlet.

In the drawings Fig. 1 is an elevation, partly in section, showing thefumigator assembled.

2 is a detail ofthe container, the body and cap being separated.

Fig. 3 is a perspective view of the stand or support.

The improved fumigator. comprises a generally cylindrical stand orsupport 1' having a bottom and open at the top. I 'The stand is providednear the bottom with a series of air intake openings 3, and nearits top,

with openings i. A heating means 5, here ticular detail, so longassufficient heat is 7 generated within the support. r V The containeris in the form of a can body Specification of Letters Patent. PatentedApr. 18, 192 2.

6, filled with, for example, paraformalde hyde, and having a tightfittingcover 7, with a funnel-like vapor. outlet 8. The cover has alateral flange 9 formed with an annular depending rib 10.

The container is applied to the stand with the flange 9 restingupon theupper edge thereof, the rib; 10 acting as a distance ele-" ment." Bythismeans the container isspaced from the support-so thatthe flame or hotproducts from the heater 5 may directly l reach a comparatively largesurface of the 1 container and more effectively and quicklyvolatilize.theicontents thereof; The openingst in the support'providefor the escape" of'the products of-combustion, andit fre i quentlyhappens that flame from the heater will reach through these openings. Itis of' importancethat this flame be prevented from.

igniting thevaporissuing from theoutlet 8,

audit is .i'orthe'i deflection ofsuch flame from the vapor. that theflange 9-.is provided.

Thisflange projects beyond the support'to an'e'xtent providing foritseffective service as a complete barrier to the flame, and hencematerial.

Havmg all possibility;of igniting the disinfecting described myinvention,I claim *A iumigator including a support having openings nearthe upper'and lower edges thereof, acontainer adapted to be arrangedwithin the upper end of the support and 7 having a diameter less thanthat of the sup-1 port, and a cover for saidcontainer having an outletand adapted to engage the container with sufficient friction tosupportthe container from the cap, said cap havinga rib formation at thelower end thereof of an exterior dimension'corresponding tothe interiordiameter of the support, whereby said rib serves to center the containerwithin and spaced from the wall of the support to expose the fullsurface of such container.

In testimony whereof I afiix my signature.
